TU RN-TABLE.

SPECIFICATION forming part of Letters Patent No. 615,295, dated December 6, 1898.

Application filed January 6,1 898. Serial No. 665,73 '7. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM R. MILES, a citizen of the United States, residing at Danbury, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Turn-Tables for L0- comotives; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable others skilled in the art to which it appertains to With this end in View I have devised the simple and novel rotating mechanism for 10- comotive turn-tables which I will now describe, referring by letters and numbersto the accompanying drawings, forming part of this specification, in which- Figure 1 is a partial sectional view showing in elevation a turn-table with my novel rotating mechanism applied thereto, a locomotive appearing in outline on the turn-table; Fig. 2, a plan View of a turn-table having my novel improvements applied; Fig. 3, a section on an enlarged scale on the lineosw in Fig. 1; r

Fig. 4, a plan View corresponding with Fig. 3, the ties and rails being removed; and Fig. 5 is an end View, as seen from the left in Fig. 3, the tie to which the motor is attached being in section.

A denotes a locomotive turn-table as a whole, which may be of any ordinary or preferred construction.

As the construction of the turn-table is not of the essence of my invention I shall not'describe it in detail.

B denotes a circular rack the teeth of which face upward and which are engaged by a gearwheel 0, mounted on a bracket 1, the base of said bracket being shown as bolted to one of the ties 2. y

D denotes a steam-motor the base of which is shown as bolted to the same tie and the shaft 3 of which carries a pinion 4, which meshes with gear-wheel C. It will be seen that the motor D and the driving gear-wheel C are hung on the moving part of the turn table directly over the circular rack B, so that thenecessity of using connecting-gears and shafts to transmit power from the motor D to the driving gear-wheel C is obviated.

- E denotes the induction-pipes of the motor, one of which extends to one end of the turntable and the other to the other end of the turn-table, each pipe being provided near its outer end with a cock 5.

Only one of the induction-pipes E, which are carried by the moving part of the table, runs across the turn-table, thus giving a motor which is much more compactand connections much less complicated than some of the turn-table-actuating devices now in use.

When the locomotive is run onto a turntable from either direction,connection is made with one of the induction-pipes E in the same manner that steam-heating pipes or air-brake pipes are connected.

6 denotes afiexible pipe, shown in the present instance at the rear end of the tender, which is provided with a coupling 7, and is adapted to be connected with either of the induction-pipes E.

The operation is so simple as hardly to require explanation. Itissimply necessary after a locomotive has been run onto the turn-table that connection between the boiler of the 10- comotive and one of the induction-pipes E on the turn-table be effected in any suitable mannor, as by means of the flexible pipes 6. The operator then opens the cock in the induction- ,pipe E,with which connection has been made,

and allows steam to pass to the motor. The motor may be the simplest form of fan-motor, having a shaft 3, which carries the pinion 4. Pinion 4 engages gear-wheel C, which in turn engages the circular rack, and thus imparts rotation to the turn-table.

Having thus described my invention, I claim In a locomotive turn-table, the combination with a suitable pit, of a rotatable table centrally pivoted in said pit,a horizontally-placed circular rack near the outer edge of said pit, a vertically-disposed gear-wheel depending from said rotatable table and meshing with said rack, a steam-motor adapted to be driven by steam from the locomotive carried by said rotatable table in proximity to the said gear- Wheel, a pinion on the motor-shaft meshing "With said gear-Wheel to drive the latter and cause the rotation of the turn-table, and independent in duction-pipes leading from each end of the turn-table to the said motor, so that a supply of steam for the motor may be readily obtained from the locomotive what- :0 ever its position upon the said rotatable table, substantially as described.

In testimony whereof I affix my signature in presence of two Witnesses.
